Erosion & Sediment Control

E&A’s Environmental Scientists help owners, developers and government agencies identify and overcome potential environmental conflicts by performing regular inspections determined by project stage and recommending actions for remediation if needed. They also assist with Silt Basin Closures & Inspections.

If a project disturbs more than one acre of land, Stormwater runoff must be regulated and a Storm Water Pollution Prevention Plan (SWPPP) prepared. Permits must be obtained, authorizing Construction Stormwater Discharges. To comply with the National Pollutant Discharge Elimination Systems (NPDES) Permit, site inspections are conducted weekly, biweekly and monthly depending on activity and stabilization, or within 24 hours of a storm event that produces at least 0.5 inches of rain. Failure to comply with any of these requirements can result in city, state and federal penalties.
